2 Signal Path and Control Circuitry
The LMK1C1108EVM supports single-ended inputs up to 250 MHz. For more information about the LMK1C1108, see the LMK1C1108 product data sheet available for download from the TI Web site (www.ti.com).
3 Getting Started
The LMK1C1108EVM has self-explanatory labeling and uses similar naming conventions as the LMK1C1108 product data sheet. In this user’s guide, all words in boldface reflect the actual labeling on the EVM.
4 Power-Supply Connections
Connect the power-supply source and ground to the terminal block labeled J1 as shown in Figure 4-1. Alternatively, connect the power-supply source to TP1, and connect the ground of the power-supply to TP2. Decoupling capacitors and a ferrite bead isolate the EVM power from the LMK1C1108 device power pins.
